The latest survey came from Rassmussen Reports, and showed Vitter
with a 54 percent to 33 percent lead, with 5 percent saying they
preferred another candidate and 7 percent undecided. The automated
telephone poll of 500 likely voters comes after two other recent
surveys showing Vitter with a double-digit advantage over his top
Democratic challenger as he seeks a second six-year term, though the
other polls showed Vitter with a somewhat less commanding advantage.

Vitter's 21-point edge also follows a June poll by Rassmussen that
found Vitter with a 19-point lead, which suggests that two months of
steady attacks by the state Democratic Party on Vitter's personal
character and the legal problems of a former aide have done little to
damage the incumbent's standing with voters.

The Democrats' latest missive is a slickly produced
documentary-style Web video made to look like a true-crime TV show that
delves into the details of Vitter's 2007 prostitution scandal. Although
the video reveals no new information about the case, where Vitter
confessed to a serious sin after his telephone number was discovered in
the logs of the infamous D.C. Madam, it managed to win publicity in a
host of national political websites.
